Too Skinny?

So ever since I could remember I was always insecure about how skinny I was. I eat when I can and have gained weight on my hips, but other than that I'm pretty little. I'm 5'3 and average around 102-104 pounds. My BMI score is technically like .1 under healthy weight, so I'm considered underweight. What do you think? Please be honest. To me I usually don't like how my body looks and I wish I was more filled out, but others say I'm a good-skinny, even if you can see a rib or two when I'm standing normally.
